I'm an HVAC guy here. Ran into one of my pumps that had its bearing fried. Took a closer look and it's a 10hp motor with 6 leads. My service guys typically deal with 9 lead motors. There are 3 diagrams on the motor itself, a "Starting", one named "Delta running". The leads were wired according to the "starting" diagram. I purchased (I thought I purchased) a DOL motor but it sounds like I got a Wye-Delta motor. Did the wiring cause the bearing failure? Also, is 6 leads for a 208-230/460V motor unusual? Thanks
